![]() ![]() Cooler temps keep the balls harder and higher elevations with less air friction fly farther. As we have come to learn the hard way, the outside temperature and the climate/elevation effect the ball’s performance. We’ve all experienced ball compression diminishing with increasing humidity and temperature during tournaments. ![]() The table values shown above are not intended to be an exhaustive collection of possibilities.Ī 52COR/275lbs compression ball by definition is a sock! ![]() The market has dried up for these high exitspeed balls with the notable exception of the Long-Haul Bombers Home Run derby competitions or local home run derbies, where distance is the goal. It’s hard to find softballs today that are 525lbs compression or higher as they are found to be too hot for our senior bats. The balls that perform the best are the COR=44 or COR=47 coupled with a high compression value of 400lbs or 450lbs. Note: Don’t confuse COR with “core” which is the center of something, as they sound the same when pronounced. Remember, the higher the ball COR value is results in less barrel compression. 52 COR would reach a greater height off the pavement. Consequently, a very high COR rating will not compress the bat barrel as much, which in turn will not maximize ball-exit-speed and distance. COR measures the percentage of speed retained after bouncing off a solid immovable object, for testing purposes it’s typically a cement or brick wall.Ī softball with a high COR value, has an affinity to “bounce” off any hard surface it comes in contact with, like a solid wall or a softball bat. This value indicates how much energy is left over after the ball strikes the immovable object and then bouncing back at a speed lesser than its incoming speed. Coefficient of Restitution) is how much is given back after the impact with a solid wall during testing. A baseball is ~9.25 inches in circumference and ~2.95 inches in diameter, and weighs ~5.25 ounces.ĭefinition: Ball compression rating describes the stiffness or hardness of the ball, Coefficient of Restitution or COR, describes the “bounciness” of the ball. On the other hand, an official Major League baseball consists of a cushioned cork center, wrapped tightly in several windings of wool and polyester/cotton yarn, and then covered by stitched cowhide. The cover is sometimes leather or more commonly a composite material. a synthetic polymer) with a cover stitched and glued to the core. Unlike baseballs, softballs have an inner polyurethane ball-core (e.g. Softballs have a circumference of ~12 inches and a diameter of ~3.8 inches, and weigh about 7 ounces. a baseball are disparate in their manufacturing processes. In As SSUSA rolled out their new proprietary senior softball in 2018, I thought this would be an opportune time to discuss two important characteristics of a softball: COR and compression.
